Idling Stop ECUs

Our idling stop ECU plays two roles: controls the start motor and controls the battery charger. In addition, the ECU is for environmentally-friendly vehicles that integrate all the main functions that are needed in electrical components used for motorcycles.

Conventional motorcycles generally have a structure with two motors: a startup motor and a battery charging motor. However, a system that uses this ECU is able to control the startup and battery charging on one motor.

Use and Compatibility

Features

Provides smooth engine startup and supports idling stop

Start motor control, charging control, and ignition and injection control can all be handled on one ECU, as well as offering idling stop, low gas emissions and low fuel consumption.

The start motor control circuit and charging control circuit both use the same MOSFET 3-phase fully controlled bridge circuit, and the control system uses phase control. Our own MOSFET is used and features the lowest loss in its class, which helps reduce the heat that is generated and make the unit more compact.

LED H/L onboard driver

The ECU is equipped with a LED H/L driver that uses a fixed-current converter. This produces stable lighting even when there is battery voltage fluctuation, load variation or temperature fluctuation.

Supports 48 V batteries and offers assist control using the starter ACG

The role of the starter control up until now was only starting and charging. However, our high output starter ACG supports a 48 V battery, which enables it to assist the engine during startup and acceleration, making the acceleration smoother and improving the fuel economy.
